I can agree to such a general information. > There is no benefit in terms of performance It might be possible that a good compiler can also optimise some unnecessary variable accesses away. Examples for further background information: * "Minimize local variables" https://eventhelix.com/realtimemantra/basics/optimizingcandcppcode.htm#Minimize%20Local%20Variables * "Temporary Objects" by Danny Kalev http://www.informit.com/guides/content.aspx?g=cplusplus&seqNum=198 > or understandability in dropping the variable. I guess that we have got different opinions on such an aspect. * Do you really want to assign every return value from a function call to an extra variable before it is used again? * How many reading and understanding capacity do you need for each extra variable?
